Cleveland has accelerated its traffic camera program this year, deploying 15 mobile units and a dozen more fixed-location cameras. We help you navigate the most frequent traveling ticket traps and advise what to do if you get nabbed.

Plus, we made the below map to show where the 15 mobile cameras have appeared at least three times from Jan. 1 to July 1.

Cleveland's traffic cameras are on the move, trying to stay ahead of you. The city now deploys 15 mobile speed cameras, and they're catching thousands more motorists a month than the 46 red-light and speed cameras permanently installed at 32 locations. (The city has also added a dozen more fixed cameras.) "They're slowing down at the fixed locations," says Maureen Harper, spokeswoman for Mayor Frank Jackson.

The roving cameras are meant to lighten your lead foot everywhere. "It helps people remember to obey the speed limits," Harper says. "We do believe it does improve safety."

The city moves the cameras every two to three weeks and announces the new locations on its blog, clecityhall.com. It alternates between two lists with minor variations.

Fight Club

MAN CAN BEAT MACHINE.Last year, drivers who appealed a camera ticket to a city hearing officer had a 47 percent chance of a reduced fine or dismissal. If your license plate looks fuzzy in the picture, you may be in luck. Common reasons for leniency include glare on plate, clarity of plate, dark environment, car obstructed view and weather condition. ¶ An appeals court has declared the camera program unconstitutional because drivers can't take tickets to court. The Ohio Supreme Court should rule on the issue within months. Stourton Scott Smith, a local attorney who handles traffic cases, says ticketed drivers should ask for a dismissal due to the appeals court ruling, and if that doesn't work, file a motion in the Cleveland Municipal Court. But beware: Unpaid tickets can go to collections, and your car can be impounded and a block can be placed on your registration.
